DuraVent Model BV Draft Hood Connector: the fitting that starts the vent at your appliance
The DuraVent Model BV Draft Hood Connector is the fitting that joins an appliance’s draft hood, its exhaust outlet, to the double wall vent above it. It screws onto the hood to form the start of the vent run. It also accepts single wall connector pipe when that is how the appliance connects to the vent. The pipe’s crimped end slips into this fitting and is held with three screws. Single wall connector pipe belongs in the open room, not through a ceiling. Model BV is DuraVent’s Type B gas vent, the double wall pipe that carries the exhaust from a gas furnace, boiler, or water heater out of the house.
Choose a diameter from 3 to 8 inch on this page. One connector already comes with the roof top kit, so check whether you need a separate one. This vent serves approved natural gas or propane appliances that use natural draft, meaning the warm exhaust rises on its own. Need a longer 4 inch fitting? See the DuraVent Model BV Extended Draft Hood Connector. The DuraVent Model BV Draft Hood Connector ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
